I am looking for a list of occupations with corresponding SEI scores using Duncan’s Socioeconomic Index. I see that you have both “occ” and “sei” in the dataset, but I can’t find a crosswalk that lists each “occ” with a corresponding “sei” score attached to it.

Unfortunately, we do not have a crosswalk available on the IPUMS website. However, by creating a data extract with SEI and the occupation variables of interest, you could create your own crosswalk(s). Keep in mind that SEI is based on OCC1950 but we do have crosswalks available for various occupation variables here.
